Why did trade increase in the roman empire

Some of the territories conquered had vast supplies of gold, good farmlands and other resources the Romans wanted.

Because as the Roman Empire increased, they had more land. And Since they had a more variety of land, they had access to more products that other cultures had and they didn't. So they were able to have more trade with the newer products they had acquired as the empire expanded.
